HENRY H. BOENKER, OF ST. CHARLES MISSOURI.

WHEEL-PLOW.

SPECIFICATION forming part of Letters Patent No. 730,737, dated June 9,1903.

Application filed February 7, 1903.

To all whom, it may concern.- 7

Be it known that I, HENRY H. BOENKER, a citizen of the United'States,residing at St. Charles, in the county of St. Charles and State ofMissouri, have invented certain new anduseful Improvements in WheelPlows, of which the following is a specification.

This invention appertains to agricultural machines designed mostespecially for tilling the soil, being applicable to plows andcultivators mounted upon rolling supports.

The invention is directed to the mechanism whereby the implement isadapted to be steered or directed in its travel over the field, thespecial advantages being tofacilitate the turning of the machine at theend of a row preliminary to recro'ssing the field.

While the invention'is shown applied in the accompanying drawings to aplow or'cultivator of the disk type, it-is to be understood that it maybe used in connection with implements having plows or earth-treatingdevices of any variety.

For a full'description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand drawings hereto attached.

While the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which Figure 1is a perspective view of a'wheel}. plow or disk cultivator, showing theapplica'-. tion of the invention. Fig. 2 is a top plan view, the ridingattachment and gang being omitted and the dotted lines showing therelative position of the parts when the tongue is moved to the right.Fig. 3 is a View similar to Fig. 2, showing the position of the partswhen the tongue is moved to the left at its front end, the dotted linesshowing independent adjustment of the ground -wheels by means of thehand-lever. Fig.4 is a central longitudinal section about on the'line -XX of Fig. 2. Fig. 5 is a front view. Fig. 6 is a perspective view of theswing-stop. Fig. 7 is a perspective view of the inner end portion of thetongue and the standard applied thereto.

Corresponding and like parts are referred the rear ends of the levers11.

Serial No. 142,383. (No modeld to in the following description andindicated in all the views of the drawings by the same referencecharacters.

The implement comprises the axle 1; ground-wheels 2 and 3; frame 4,mounted upon theaxle; tongue5; and adjunctiveparts for adjusting thedifferent elements, such as will be described more fully hereinafter.

The riding attachment 6 may be of any variety and is coupled to the axlein any accustomed way. The plow or cultivator gang 7 may be of any type,and as illustrated is of the disk variety and is coupled to the axle inthe usual way.

Brackets or curved standards 8 are applied to the ends of the axle 1 andterminate at their upper ends 'in vertical hearings or sleeves 9, inwhich are mounted the stems 10 of the frames carrying the respectivegroundwheels. The stems are adapted to turn and move vertically in thebearings 9 to allow for propensteering and regulation of the depth ofplowing or cultivation. Operating-levers 11 are fulcrumed to the upperends of the stems'10 and are connected by links 12 to lugs 13, projectedlaterally from the standards 8 in a'forward direction, thereby admittingof the levers extending within convenient reach of the drivers seat.Toothed segments 14 are provided at the upper ends of the stems 10, andspring-actuated latchbolts 15, applied to the levers 11, cooperate withthe teeth of the segments 14, so as to hold the levers and the axle inthe required adjusted position, the latch-bolts being operable by meansof hand-latches l6, pivoted to The links 12 are of such construction andare attached to the respective parts in such manner as to admit of thestems 10 turning freely in either direction, according as the machine isturned either to the right or to the left.

The frame 4 is capable of adjustment along with the axle and is securedin the located position by means of olampscrews 17. A ledge or shelf 18projects horizontallyfrom the rear of the frame 'and is in a lower planethan the top of the axle to form'an offset or shoulder 19, against whichthe swing-stop is adapted to engage to limit its movement. Stops 19 and20 project upward from the frame 4 and limit the lateral movements ofthe tongue 5, said stops having adjustable con nection with the frame toadmit of changing the degree of movement ofthe tongue. The stops 19 and20 preferably consist of grooved rollers mounted upon pins, so as toreduce the frictional engagement of the tongue when in contacttherewith, the groove of the rollers receiving the edge portion of thetongue, so as to prevent upward displacement thereof.

The swing-stop 21 is pivoted to the rear extension 18 of the frame 4 bymeans of the pin or fastening 22 and consists of a block having theadjacent edges 23 and 24 arranged at an obtuse angle and adapted toengag with the shoulder or olfset 19, so as to limit the turning of theswing-stop in each direction. The tongue 5 is pivoted at its rear end tothe swing-stop at 25 and is provided at its front end with ahammer-strap 26 and a series of openings 27 for adjustable connectiontherewith of the draft. The tongue passes over the frame 4 and reststhereon and is adapted to move between the stops 19 and 20. A

standard 28 rises vertically from the rear por- .series of openings 30to hold the lever 34 in an adjusted position. The parts 33 and 34 may beintegral with or rigidly applied to the shaft 32.

The frames supporting the ground-wheels 2 and 3 are provided withforwardly-extended arms 36 and 37, having aseries of openings in theirlength for adjustable connection therewith of a transverse bar 38. Thisarrangement admits of simultaneous movement of the ground-wheels in thesame direction. A pivoted bar 39 is adjustably connected to the bar 38and arm 33 by means of links or connections and 41. The link orconnection 40 is com posed of sections connected by means of aturnbuckle 42 to admit of lengthening and shortening, so'as to adjustthe bar 38 and ground-wheels with reference to the pivoted bar 39. Thebar 39 is pivoted to a casting or like support 43, mounted upon the axle1 and secured thereto in an adjusted position by means of a clamp-screwor like fastening. The links or connections 40 and 41 admit of verticaladjustment of the axle 1 when shiftstop 21 moves upon itspivot-fastening 22 until the edge 23 comes in contact with the shoulder19, as indicated most clearly in Fig. 3. When'the draft is applied so asto move the front end of the tongue to the right, as indicated by thedotted lines in Fig. 2, the tongue turns its pivot connection 25 withthe swing-stop and bears against the top 19. In the several movements ofthe tongue the ground-wheels correspondingly move, as indicated in thedifferent views, to correspond with the position of the tongue, therebyfacilitating steering and turning of the machine. The hand-lever 34provides for independent steering or directing of the implement, asindicated by the dotted lines in Fig. 3. The draft may be straightahead, whereas the shifting of the hand-lever 34 either to the right orto the left causes the machine to swerve from a direct course to steerclear of an obstacle or to follow the irregularities of a row of plantswhen cultivating or to properly diroot the implement for any purpose.The ground-wheel 2 and the ground-wheel 44 of the riding attachment areinclined away from the furrow side of the machine in the usual may tocompensate and resist lateral stress.
